Exempel på hur man kan använda BACKWASH i en mening

• Breaking surf sends water up the coast (swash) at an oblique angle and gravity then drains the water straight downslope (backwash) perpendicular to the shoreline.
• The Punchbowl on Turkey Run's Trail 3 is an example of a pothole that was scoured out by glacial erratics caught in swirling backwash.
• Paul Mosley termed this the micro-macro paradox and offered three potential explanations: inaccurate measurement, fungibility, and "backwash" or negative side-effects of component aid projects.
• The backwash cycle is triggered after a set time interval, when the filter effluent turbidity is greater than a treatment guideline or when the differential pressure (head loss) across the filter exceeds a set value.
• Coarser sediment allows percolation during the swash part of the wave cycle, thus reducing the strength of backwash and allowing material to be deposited in the swash zone.
• The beachface is in dynamic equilibrium with swash action when the amount of sediment transport by uprush and backwash are equal.
• Channels begin to form headward in the form of millimeter wide rills along the sides of the fans; the creation of these small channel networks culminates when the last of the backwash dissipates.
• Lamella clarifiers can be used in a range of industries, including mining and metal finishing, as well as to treat groundwater, industrial process water and backwash from sand filters.
• Backwash breaking parallel to or obliquely to the angle of the shore is sometimes also called sidewash, which can form from the reflection of a wave breaking against adjacent obstructions such as jetties, groynes, or rockwalls, or simply from the action of backwashing waves which strike a shoreline at an angle.
• In use from World War I through the Vietnam War, it has been replaced by reverse osmosis systems that produce potable water by pressure straining local water through microscopic-level filters: the Reverse Osmosis Water Purification Unit (1980) and the Tactical Water Purification System (2007) for large-scale production, and the Light Water Purifier unit for smaller-scale needs that includes ultrafiltration technology to produce potable water from any source and uses automated backwash cycles every 15 minutes to simplify cleaning operations.
